There's not much detail about the project, only this description: "A prototype jockey-ridden hopping robot that controlled forward speed, hopping height, and pitch balance, the jockey did sideways balance and steering."

While this thing is really cool, I'd have to submit that it is no more a robot than is say, a motorcycle. Give it some gyros and a servo control system so that it can self-balance, then it's getting closer to a robot.
